Title (EN) ROTARY COMPRESSOR AND ASSEMBLY METHOD THEREOF
(FR) COMPRESSEUR ROTATIF ET SON PROCÉDÉ D'ASSEMBLAGE
Abstract:
(EN) A rotary compressor that may include an upper or outboard bearing above the motor components and, in this case, includes an upper bearing plate having a structure that ensures bearing alignment when press fit with an upper cap and a center shell. In some implementations, a main bearing frame that secures and holds a main bearing has a structure that when press fit with a lower cap and center shell ensure bearing alignment. Some implementations include disposing a hermetic terminal and a discharge port a the side of the upper cap or center shell.
(FR) La présente invention concerne un compresseur rotatif qui peut comprendre un palier supérieur ou extérieur au-dessus des composants de moteur et, dans ce cas, qui comprend une plaque de support supérieure ayant une structure qui assure l'alignement de palier lorsqu'elle est ajustée serrée sur un capuchon supérieur et une coque centrale. Dans certains modes de réalisation, l'invention concerne un cadre de palier principal qui fixe et maintient un palier principal, lequel cadre de palier principal a une structure qui, lorsqu'elle est ajustée serrée sur un capuchon inférieur et une coque centrale, assure l'alignement de palier. Certains modes de réalisation comprennent la disposition d'un terminal hermétique et d'un orifice de décharge sur le côté du capuchon supérieur ou de la coque centrale.
